Single-Chip 60-V eFuse with Reverse Polarity Protection

October 31, 2016 by Jeff Shepard

Texas Instruments (TI) has introduced a single-chip eFuse with back-to-back FETs, claiming the industry's highest rating of protection at up to 60V. Offering on-chip advanced features including reverse polarity protection and reverse current blocking, the TPS2660 is the most-integrated eFuse on the power management market for 24-V and 48-V rail applications in industrial, automotive and communication infrastructure designs.

Key features and benefits of the TPS2660 eFuse include, Integrated back-to-back FETs: The device’s unique architecture, enables reverse polarity protection to help guard the system load from miswiring, which can occur in industrial equipment that use screw terminals. Reverse current blocking prevents current from flowing backward from the output side to the input side.

And advanced protection and integration reduce board space up to 40 percent by eliminating the need for external components. Adjustable overvoltage protection up to 60 V: Helps designers pass industry-standard surge-compliance tests more quickly and reliably, including the electrical fast transient (EFT) test.

The eFuse is available now in the TI store and through the company’s authorized distribution network. The TPS2660 comes in a 4.4-mm-by-5-mm thin shrink small outline package (TSSOP) and is priced at US$2.20 in 1,000-unit quantities.
